Write a system of equations to describe the situation below, solve
using any method, and fill in the
blanks.
In a paint factory, an old conveyer
line has filled 32 barrels of paint,
and is filling more at a rate of 7
barrels per minute. A worker just
switched on a newer line that can fill
9 barrels per minute. In a little
while, the two lines will have filled
an equal number of barrels. How
long will that take? How many
barrels will each line have filled?
